Why this glossary exists
This short guide explains the most common words you will meet on Triathlon Quest. It helps the reader understand the sport quickly and train smarter in Boulder and beyond.
Race Basics
Brick — A workout that combines two disciplines back to back, usually a bike ride followed by a run. It teaches the body to switch gears smoothly; this is exactly how race day feels.
Drafting — Riding closely behind another athlete to save energy. It is allowed in some races and banned in others; check the rules before you line up.
Fatriathlon — A fun, inclusive format that welcomes heavier athletes and beginners. Distances are often shorter so the reader can finish strong and build confidence.
Transition — The area where you change gear between swim, bike and run. Smooth transitions save minutes; practise them like any other skill.
Training Terms
Aerobic base — The foundation of steady, easy training that improves fat burning and endurance. Build it first; without it, speed work breaks down fast.
Bonking — Running out of energy mid-race because glycogen stores are empty. It feels like hitting a wall; eat and drink early to avoid it.
Heart rate zones — Five training intensities based on your maximum heart rate. They tell the reader exactly how hard to push each session.
Open-water swim — Swimming in a lake, river or sea instead of a pool. Sighting and dealing with waves become normal skills; most Boulder races use this format.
Threshold — The highest effort you can hold for about one hour. Train just below it to raise your sustainable race pace without burning out.
Gear and Nutrition
Aero bars — Handlebar extensions that let the reader ride in a low, tucked position. They improve speed on the bike; adjust them carefully to protect your back.
Gels — Small packets of quick carbs designed for use during long efforts. They replace energy fast; test flavours in training, not on race day.
Wetsuit — A neoprene suit that adds buoyancy and warmth in cold water. It makes swimming easier; choose the right thickness for Boulder’s mountain lakes.
Wheelset — The pair of wheels on your bike. Lighter or deeper wheels can save time; upgrade them only after you have built a solid aerobic base.
